钠离子电池为什么近年突然爆火？

Why has Sodium-ion Battery suddenly become popular in recent years?    

钠离子电池近年突然爆火，是市场需求、技术突破、资源瓶颈、政策扶持四大核心因素共同推动的结果，是新能源产业发展的必然趋势。首先，市场需求爆发，全球双碳战略推动下，新能源发电、储能、电动车市场快速增长，对电池的需求呈指数级上升，尤其是储能市场，需要大规模、低成本、高安全的电池，钠电池完美契合这一需求；其次，技术实现突破性迭代，2020年前后，钠电池正负极材料、电解液、生产工艺取得重大突破，能量密度、循环寿命、安全性大幅提升，实现了从实验室到产业化的跨越，具备了大规模商用的条件；第三，锂电池资源瓶颈凸显，锂、钴、镍等稀有矿产价格暴涨，供应链波动剧烈，资源垄断问题突出，而钠资源储量丰富、随处可得，彻底摆脱了稀有矿产的制约，成为新能源电池的核心替代方向；第四，政策大力扶持，我国将钠电池纳入新能源产业、双碳战略重点发展名录，多地出台政策支持钠电池产业化、储能项目落地，为钠电池的发展提供了良好的政策环境。多重因素叠加，推动钠电池近年快速爆火，成为新能源产业的核心风口。

The sudden popularity of Sodium-ion Battery in recent years is the result of the joint promotion of four core factors: market demand, technological breakthrough, resource bottleneck, and policy support, which is an inevitable trend in the development of the new energy industry. First of all, the market demand has exploded: driven by the global dual carbon strategy, the markets of new energy power generation, energy storage, and electric vehicles have grown rapidly, and the demand for batteries has increased exponentially. Especially in the energy storage market, there is a huge demand for large-scale, low-cost, high-safety batteries, which are perfectly met by sodium batteries; secondly, technological breakthroughs have been achieved: around 2020, major breakthroughs have been made in the cathode and anode materials, electrolyte, and production process of sodium batteries, and the core performance indicators such as energy density, cycle life, and safety have been greatly improved, realizing the leap from laboratory to industrialization, and having the conditions for large-scale commercial use; thirdly, the resource bottleneck of lithium batteries has become prominent: the prices of rare minerals such as lithium, cobalt, and nickel have skyrocketed, the supply chain has fluctuated violently, and the problem of resource monopoly has become prominent. While sodium resources are abundant and readily available, which completely gets rid of the constraints of rare minerals and becomes the core alternative direction of new energy batteries; fourthly, strong policy support: China has included sodium batteries in the key development list of the new energy industry and the dual carbon strategy, and many local governments have introduced policies to support the industrialization and energy storage project implementation of sodium batteries, providing a good policy environment for the development of sodium batteries. The superposition of multiple factors has promoted the rapid popularity of sodium batteries in recent years, making it the core outlet of the new energy industry.
